Step 05.4 — Test-fit T-nuts and stage the fasteners¶
Step 4 of 48 with a helper · Chapter 05 — Gantry: X and Y axes, XY joints, X carriage, titanium backers
Parts:
- M5 roll-in T-nut ×26 · set out now, fitted later
- M3 roll-in T-nut ×58 · set out now, fitted later
Do:
- Roll one M5 and one M3 T-nut through each face of all four extrusions.
- Mark any face that binds with tape.
- Count the fasteners out into labelled trays per the hardware table above.
Check
Every T-nut you will use rolls in without force; a forced nut galls the channel.
Helper Counts the T-nuts and bolts into their piles and checks them against the list.
What you're looking at
A roll-in T-nut drops into an extrusion slot and rotates a quarter turn to lock, and almost every bolt in this chapter pulls against one. The renders show the four extrusions, E, both C beams and D, with every T-nut already in its slot.
Tip
The CAD extrusions are the 250 lengths (E 240, C 350, D 330 mm); yours are the 350 set. Which faces carry nuts, and how many, is what transfers.
Good stopping point · ~25 min since the last one
bench cleared, sub-assemblies laid out left/right, T-nuts test-rolled and counted into trays. Nothing is assembled; leave the trays covered so nothing gets swept off.
